5b7b0ce861 Limit the size of the space reserved for code on systems that 
are short of virtual memory.  This should make V8 work in 64 bit
on OpenBSD in its default configuration.  It is a simplified
version of the reverted 8133 which also lowered the non-code
heap size, causing test failures in Chromium on MacOS.

0bb0d672b6 Make ToBooleanStub more consistent across platforms. 
The declaration of the ToBoolean class moved to the platform-independent part
and its implementations are now structurally very similar. This is just an
intermediate cleanup step to add type recording at the call site.

Note that the MIPS implementation has not really been touched, so it should
continue to work, too.

A multi-line comment containing a newline is considered a line-terminator for

af24067fa5 Refactor the way we collect the information for associating type-related infos 
with AST IDs. Previously 3 different places had to match in how they handle a
given case, now we are down to 2, with an even simpler logic.

The downside is that due to this simpler logic the allocated dictionary could be
larger than before, but test have shown that this happens *very* rarely, because
its capacity is rounded to the next power of 2, anyway. Furthermore, the oracle
doesn't live long enough that we should really care.

The whole oracle is probably still a bit too tricky in its details, but this is
at least a step into the right direction.

8c538d9012 Made parser not accept unicode escapes inside "native" when used as a keyword. 
This is a regression relative to the original behavior, when "native" was a keyword,
since keywords cannot contain esacpes.

480ec43c4e Make "native" not a keyword. 
We now only recognize "native function" when it occurs in extension scripts
(parsing with a non-NULL extension), and only if there is no line-terminator
between "native" and "function" (so that it would otherwise be a Syntax Error).
Preparsing never recognizes native functions, which is acceptable since we
never preparse extension scripts (because we don't allow lazy functions
anyway).
